Traffic signs are designed keeping principles of simplicity and attention in mind. The design uses shapes and colours to attract attention, and symbols to convey vital information without words, in order to eliminate language barriers. 

We explore and explain the meanings of road markings, traffic rules and traffic signs in India.

How are the traffic signs in India designed?

Designing a traffic sign is a complex combination of science and art. The main objective of a traffic sign is to convey complex information as quickly and clearly as possible. Therefore, the traffic signs are designed to attract maximum visibility and provide quick comprehension to the drivers. For this purpose, the design focuses on using high visibility colours, eye-catching shapes, and universally identifiable symbols. 

On one hand, it includes identification of user needs, and on the other, the design also needs to adhere to the psychology of colour and shapes to create traffic signs that are functional, intuitive, and cater to the diverse needs of all road users.

Before we begin discussing the shapes and sizes of the traffic signs, let us first begin by understanding the types of boards on which the traffic signs are made. In terms of print surface, there are two primary types of sign boards in India:

1. Reflective sign boards: Most commonly used sign boards for traffic signs in India, use reflective sign boards designed in a way that they reflect light from passing cars, making them highly effective in low-light conditions. It is made by crimping a reflective sheet over an aluminium plate, a durable and rust-free medium, making it a preferred choice for the highways. 
2. Internally illuminated sign boards: More common in city traffic, internally illuminated sign boards use LEDs or fluorescent lights and provide consistent visibility, even from a distance, regardless of external lighting conditions. 

These two types of sign boards form the majority of modern road signage. 

What is the standard size of traffic sign boards in India?

In India, the size of traffic signs are prescribed by the Order on Traffic Signs, Partition Lines, and Road Markings, which is also known as the Sign Ordinance. This ordinance establishes installation standards, methods, and recommendations, which are further refined by specific guidelines from expressway operators for highways. The height, or clearance, between the road surface and the bottom edge of a traffic sign varies. The sizes may also vary based on the area, speed limits, and the type of signs they are supposed to indicate.

Road signs fall into different categories with specific standard sizes. Three broad categories of traffic road signs, with their expressway dimensions, are given below (dimensions vary for highways, expressways and city roads as recommended by the Ministry of Road Transport and Highway of India):

Mandatory signs:

• For roads with speed limit between 81-120 km/h, the diameter of mandatory signs should measure 1200 mm with a 100 mm border
• For roads with speed limits between 121-150 km/h, the diameter of mandatory signs should measure 1500 mm with a 125 mm border

Cautionary or Warning Signs:

• For roads with speed limits between 81-120 km/h, the diameter of mandatory signs should measure 1200 mm with a 90 mm border
• For roads with speed limits between 121-150 km/h, the diameter of mandatory signs should measure 1500 mm with a 110 mm border

Informatory or Instruction Signs:

These signs are further categorised as Overhead Direction Signs and Flag Type Directions Signs. The board diameters may vary; however, the text sizes need to be uniform in this category. The text sizes prescribed are as follows:

• For speed limits between 101-120 km/h:
  • The Overhead Direction Signs should have the following text height: 1) 330mm in lower case, and 2) 460 mm in upper case.
  • The Flag Type Directions Signs should have the following text height: 1) 245 mm in lower case, and 2) 345 mm in upper case
• For speed limits between 121-150 km/h:
  • The Overhead Direction Signs should have the following text height: 1) 380mm in lower case, and 2) 530 mm in upper case.
  • The Flag Type Directions Signs should have the following text height: 1) 270 mm in lower case, and 2) 380 mm in upper case

The text thickness in all cases should be 50 mm for roads with speed limits between 101-120 km/h, and 60 mm for speed limits between 121-150 km/h. 

These dimensions are made mandatory keeping in mind the location specific visibility and the gravity of importance of the information conveyed. 

Types of traffic signs or road safety signs

In terms of functionality, there are five main types of traffic signs, or road safety signs in India, namely mandatory signs, cautionary signs, informatory signs, guide signs, and auxiliary signs.

• Promoting road discipline: They enforce road rules and regulations, guiding drivers to maintain discipline and follow traffic laws.
• Navigational aid: For new drivers and travellers, traffic signs provide essential guidance for navigating routes and reaching destinations safely.

The traffic sign system in India is regularly updated by the authorities to ensure a well-organized traffic management system. Various types of traffic signals are used, including hand signals by traffic police, pavement markings, and traffic light signals. By adhering to these signs, drivers not only comply with the law but also contribute to reducing accidents.

Under the New Motor Vehicle Act of 2019, stringent penalties are imposed for traffic violations, underscoring the importance of awareness and adherence to traffic signs. Knowing and following these signs not only promotes road safety but also contributes to a more orderly and harmonious driving environment in India.

Enhancing road safety: Additional traffic signs and signals in India

In addition to fixed roadside traffic signs, India employs various supplementary signals and markings to enhance road safety and streamline traffic flow. These additional signs play a critical role in guiding drivers, ensuring pedestrian safety, and maintaining order on the roads.

Hand signals by Traffic Police

Hand signals by traffic police officers are indispensable for managing traffic at intersections and accident sites. These gestures provide real-time guidance to drivers and pedestrians, ensuring smooth traffic flow and minimizing congestion. Some important signals are as follows:

• Right hand stretched out with palm facing front and making a wave gesture from the other arm to stop one side of the vehicle, and let the other side pass through, and vice versa.
• Right hand raised in front, with palm facing front. This indicates that the vehicles coming from the front must stop. 
• Left hand stretched out, with palm facing backwards. This sign indicates to the vehicles coming from behind to stop. 
• Right hand raised in front with palms facing front and left hand stretched out with palm facing backwards. This gesture indicates to the vehicles approaching from front and behind to stop. 
• Left and right arms raised, with palms facing either side. This sign is used to stop vehicles coming from left and right directions, simultaneously. 
• Right hand raised to the front, with palm facing frontwards, and the left arm bent in front of the chest and sweeping in and outwards gently. This indicates to the vehicles coming from the left side to start moving. Vice versa for the traffic approaching from the right. 
• Both hands lifted at shoulder level, and half bent towards the head, creating a diamond like shape. This sign indicates change. 

Hand signals by drivers

Hand Signals by Drivers: Drivers use hand signals to communicate intentions effectively on busy Indian roads. These signals supplement vehicle indicators, helping to navigate through traffic and ensure safety during turns, stops, and emergencies. Some important signs are as follows:

• Right turn signal: Right arm extended out, with palm facing front, before turning right. 
• Left surn signal: Right arm extended out, folded at the elbow pointing up, before turning left. 
• Stop signal: Right arm extended and raised vertically, to alert the following drivers before stopping.
• Slowing down signal: Right arm extended, and gently swung up and down. 
• Lane changing signal: Extending the right arm and rotating clockwise if changing to the right lane and anti-clockwise, if changing to the left lane. 

Road marking or pavement marking signs in India 

Road marking or pavement marking signs: Road markings are crucial visual aids that complement traffic signs. They delineate lanes, warn of hazards, and guide drivers through complex intersections. Understanding these markings is essential for safe and efficient driving across varied road conditions. Some important signs according to Delhi Traffic Police are as follows:

Centre line:

• These are white-coloured, broken lines, dividing the road into two for opposing traffic. These lines can only be crossed for overtaking, if the incoming lane is clear. 

Solid white/yellow lines:

• Solid white or yellow coloured, lines divide the road into two lanes. Crossing these lines, or overtaking is strictly prohibited.

White signs:

• These lines inform the driver to slow down and are typically found near schools, colleges, or hospitals. These markings are usually supplemented with a speedbreaker.

Small broken white lines:

• These lines demarcate lanes on a road between left lane, middle lane and right lanes. 

Parking prohibited lines:

• There are two kinds of parking prohibited lines: continuous single yellow/white lines and continuous single yellow/white lines. Single lines indicate no parking allowed, but stopping is allowed. Whereas, double lines mean neither parking, nor stopping is allowed. 

Stop line:

• These are single solid transverse lines that are found at intersections. The drivers are expected to stop before this line at signals if the light is red. 

Zebra crossing lines:

• These are thick, alternate black and white stripes, and indicate the designated area for pedestrians to cross. Usually found at the traffic signals, or at the top of the lanes, or junctions, vehicles must stop before zebra crossings to allow pedestrians to pass. 

Box junction:

• These are rectangular boxes with yellow crossed diagonal lines, meant to indicate that the vehicles must not stop within this box.

Road rage in India

Road rage is a growing concern on Indian roads, underscored by alarming statistics. Globally, several researchers have pointed out aggressive driving as the main contributor to traffic fatalities. The escalation of road rage incidents in India reflects a concerning trend of reckless behaviour on roads. Triggered by stress, impatience, and frustration, road rage poses a significant threat to public safety, creating hazardous conditions for all road users.

According to India’s Ministry of Road Transport and Highways, there were 1,55,000 road rage accidents in 2019, increasing to 1,83,000 cases in 2020, and further rising to 2,15,000 incidents in 2021. This upward trend highlights the urgent need for measures to curb aggressive driving behaviours that endanger lives. These actions not only jeopardize the safety of drivers but also put pedestrians, cyclists, and other road users at risk.

In this milieu, traffic signs serve a very important function by enforcing road discipline and setting expectations for safe driving practices. They remind drivers to maintain appropriate speeds, yield to pedestrians, and follow lane markings, fostering a structured environment that discourages reckless behaviour. When drivers consistently adhere to traffic signs, they contribute to smoother traffic flow and fewer opportunities for conflict or aggression. In essence, traffic signs serve as proactive tools for preventing road rage by promoting a culture of respect, patience, and compliance with road rules. 

Conclusion

In conclusion, traffic signs in India are not merely symbols on the road; they are essential safeguards that promote safety, order, and harmony among drivers. As we navigate the complexities of urban and rural roadways, traffic signs provide guidance, prevent potential conflicts and promote a culture of responsible driving. By adhering to these signs, drivers not only ensure their own safety but also contribute to the safety of pedestrians, cyclists, and fellow motorists. 

Let's remember that every stop, yield, and speed limit sign plays a crucial role in preventing road rage, reducing accidents, and ultimately making our roads safer for everyone. Embracing the importance of traffic signs is not just about compliance; it's about cultivating a mindset of mutual respect and collective responsibility on the journey toward safer roads in India.
